Top Medical Research Studies

We examined how quercetin, a natural compound, can help alleviate chronic cough by targeting P2X3 receptors, which are involved in cough reflexes. The study involved testing its effects on male mice and guinea pigs.

Results showed that quercetin effectively modulated these receptors without causing adverse taste effects, unlike other drugs like gefapixant. This potential opens up new avenues for treating chronic cough without unpleasant side effects.

An excellent tool! After three months, I can properly evaluate this drug. I used it for chronic cough due to allergies, particularly ragweed. My son has chronic obstructive bronchitis and found it very helpful as an expectorant. We survived allergy season and are now using it for immunity alongside vitamins C and D. We feel great!

With age, I developed high blood pressure and sought a natural approach. A doctor suggested quercetin to enhance capillary function, and within a week, my upper blood pressure readings dropped by 20. Notably, my chronic cough also improved after my son began using it as well.

Bought this after reading reviews. My daughter had a chronic cough for several months. Although antibiotics and cough mixture helped temporarily, the cough returned.
